The CPD covers Designing Lighting to Promote Better Sleep. It involves an in-depth look at what sleep is, what circadian rhythms are and light’s entrainment of them, the effect of circadian disruption on sleep and the knock-on negative effects of sleep deprivation for general health. Connected with above, shortcomings of many indoor lit environments are discussed, followed by a look at lighting recommendations which can go a long way toward solving these shortcomings. The pre

It’s almost the time of the year again, the day in autumn when the clocks turn back to natural time. Every year, millions of people groan, lose sleep, and wonder, why are we still changing our clocks to daylight saving time in the summer? The seasonal clock change is one of those traditions that perhaps made sense once upon a time but no longer serves us. In fact, modern science is increasingly clear: switching the clocks twice a year disrupts our health, our productivity, an

Good light changes lives. A peer-reviewed study “ Biodynamic lighting effects on the sleep pattern of people with dementia ” reports that good light, either daylight or light that compensates for a lack of daylight, has a substantially positive influence on people with dementia. The results are both humane and practical: better sleep at night, greater alertness by day, and less restlessness overall. What the research found Under good light conditions, residents experienced: L
